Application filed October 20,1919. Serial no. 332,029.

a work supporting table which willconven-f iently support garments of various forms in such a manner that the operator canpresent them easily to the feed and stitch forming mechanism of the sewing machine.

In the use of sewing machines a great variety of articles are operated upon including relatively small articles of tubular iform such as sleeves, trouser bottoms and the like,

and larger articles also of tubular and rectangular form such as skirts and coats and various heavy articles of considerable extent which cannot conveniently be placed upon the usual bench which supports the bed plate of the sewing machine.

The present invention contemplates the provision of a supplemental table provided with an extension overhanging the work support which will enable a large portion of the garment or large article which is being operated upon to rest upon the bench while the portion being operated upon is carried over the surface of the work supporting table to the stitch forming mechanism,

A further object of the invention is to pro vide means for detachably securing the supplemental table to the bed plate of the sewing machine so that it can be removed and the machine operated with the usual work support to stitch small tubular articles and the like. I

in sewing various articles it is desirable that the operator may grasp the work in the line of stitching closely adjacent to the.

needle. Another object of the invention therefore is to provide a work supporting table of the character described with a recess behind the stitching-lmechanism so that the hand of the operator may be brought down to the level of the work supporting surface of the work support thereby enabling the goods to be guided horizontally past the MoUL oN,

work without becoming tired.

stitch forming mechanism, a further advantage residing-Kin the fact that the operaor bed plate of the machine and guide the torcanth'en' rest the elbow upon the bench" Another object of the invention is to pro-.

vide a novel anchoring means for detachably fastening the supplemental work supporting table to the bed plate of the, machine,

Other objects and features of the inven tion will more fully appear from the following description and the accompanying drawings and will be pointed out in the annexed claims. A preferred embodiment of the invention is illustrated in the accompanying drawings in connection with a blind stitch sewing ma? chine of the Arbettertype,but it willibe understood that the invention is adapted for use inconnection with any other type of sewing machine having a work support ex tending a distance above the surface of the bed plate. In the drawings, I Fig. l is a side elevation of a sewing-mac-hiige showing the invention associated there wit i, I I

Fig. 6 is a vertical sectional view on line 1 The sewing machine illustrated in the drawing comprises a bed plate 1 which is secured to a usual bench 2, a standard 3 forming mechanismin a machine of the Y type illustrated herein comprises an'oscillating needle 6 and complemerrtary stitch form ng mechanism wnici may be of any usual character (not shown).

The presser foot 7 carried by the head cooperates with the yieldable work support 8 which is carried by a suitable standardt and extends considerable distance above the surface of the bed plate. This construction may be of a usual type but preferably the work support 8 is carried to a hi h position above the led machine standard 3 is correspondingly extended to provide a larger clearance beneath the arn to receive thematerial which is operated upon. thereby giving the machine a greater capacity.

The work suppor ing surface of the work support desirably relatively small so that mall tubular articles such as sleeves may be readily presented to the stitch forming mechanism. When larger articles however are to be operated upon it becomes inconvenient to present them to the stitch forming mechanism and the present invention has been d d for the purpose of providing a suitable and convenient support for articles o any haracter or size.

The invention broadly comprises a table dapted to be detachably secured to the bed late or"- the machine and to present a work su i' o tine srrtace which will co-operate wi supporting surface of the n the worlt wor support of the machine. the area of the table being sutlicient to support a large a ount oi" the work. The table is also des rabl provided with an extension overhan 'in z' the bench pr vidinc a suds ent space to enable a larae amount of materia to rest upon the bench out of the way the operator.

This is particularly convenient where lar e tubular articles such as skirts are beinw stitched for it enables the larger portion ot the skirt to rest upon the bench while the portion which is being sewed is carried upon the surface of the table and readily presented to the stitch forming mechanism.

preferred Iorm of table comprises a stand having a vertical front wall 10 and side wall 11 and a top 12 webs 18 and 14 e::- tending; laterally from the side wall 11. and a connectina'web 15torming a strengtheninc; support tor an extension 16 of said top. The top 12 is cut away to provide an i; shaped recess 17 to partially surround the worl-r support 8 of the sewing: machine. At the rear oi the recess the table is provided with a depressed portion. the bottom 18 of which extends downward in a gentle curve from the surface of the table as illustrated in 1, nearly to the surface 01" the bed plate. A supporting wall 19 extends from the side wall 11 alone the front of the ale-- pressed bottom 18. The table thus formed is provided with feet 20 and 21 extending downwardly from the bottom 18 05 the deplate and the sewing pressed portion, and feet 22, 23 formed integral with the front wall 10, the surface of these feet preferably being machined so as to set firmly upon the bed plate of the machine. An L-shaped plate 24; which is suitably secured to the top 12 of the table preferably surrounds the work support 8 and provides a smooth surface, upon which the goods may be manipulated by the operator, closely adjacent to the stitching point.

The depressed portion of the table at the rear of the work support enables-the operator to grasp and hold the work horizontally, thereby facilitating the operation of guiding the material past the stitch forming mechanism. This recess also enables the operator more easily to remove and replace the bobbin in machines of the character illustrated in which the rotary hook or looper is carried from a hool: bracket depending from the head of the machine.

Any suitable means may be provided for anchoring the work supporting table to the bed plate of the machine. As illustrated herein the bed plate is provided with a plurality of apertures, two as illustrated, whichare surrounded by countersunk plates 25, 26 which are secured to the bed plate by suitable screws. These plates have key slot apertures 27 and 28 adapted to receive the heads of anchoring members such as studs carried by the table.

The smaller portion of the key slot apertures preferably converge toward each other and toward the work support so that when the studs are inserted through the apertures and caused to approach toward each other the table will be firmly clamped to the bed plate and drawn to its proper position in relation to the work support.

Any suitable locking; means may be used to connect the table to the key slot apertures, a convenient means which is illustrated herein comprises a stud 29 seated in a boss 30 projecting downwardly from the inside of the bottom 18 of the depressed portion of the table, said stud having an enlarged head 31 adapted to pass'through the enlarged portion of the key slot but too large to pass through the narrower portion thereof and a co-operating adjustable stud of a similar character.

A preferred form of adjustable stud which is illustrated in detail in Fig. 4% comprises a bar 32 pivotally secured at its upper end upon a stud 33 mounted in suitable bosses 34, 35 extending rearwardly from the front plate 10 and having at'its lower end a stem 36 terminating in a head 3? adapted to enter the enlarged portion of the hey slot.

The position of the bar 32 may be ad justed by a screw 38 having an end portion 39 or" smaller diameter extending through. the bar 32 and rotatably secured therein by screw to seated in the bar 32 and engaging in a slot 41 in said screw. The screw threaded portion of the screw 38 extends through a boss 42 upon the front wall 10 and through the wall 10 itself. The head 43 of the screw 38 may be provided with a transverse hole at adapted to receive a screw driver or other lever suitable for applying considerable power to the screw.

In operatin the machine upon small articles the table may be removed and the stitching done upon a machine in the usual manner. When larger articles are to be stitched the table may be associated with the work support of the machine by merely placing the table upon the bed plate in such a manner that the heads 31 and 37 of the studs will pass through the key slot apertures 27 and 28 in the plates 25 and 26, the screw 38 then being set up to cause the pivotally mounted bar 32 to be moved inwardly, thereby forcing it toward the stud- 29 and causing the heads 31 and 37 to lock the table firmly to the bed plate of the machine. The operator may then place a part of the work upon the bench, carrying such portion as is to be stitched over the extension 16 and thetop 12 of the table to the stitch forming mechanism. Whenthe goods have been presented to the needle, the operator may, by reaching around behind the arm 4: and head 5, grasp the work immediately behind the stitching point and thereby manipulate it much more easily than in usual machines. a

It will be understood that the invention illustrated herein is illustrative and that 'various changes in construction and arrangement of parts may be made within the meanin and scope of the following claims.
